| Inheritance | Object → Bitmap → WriteableBitmap |
Constructors
| WriteableBitmap(PixelSize, Vector, Nullable(PixelFormat), Nullable(AlphaFormat)) | Initializes a new instance of the WriteableBitmap class. |
| WriteableBitmap(PixelFormat, AlphaFormat, IntPtr, PixelSize, Vector, Int32) | Initializes a new instance of the WriteableBitmap class with existing pixel data The data is copied to the bitmap |
Properties
| AlphaFormat | (Inherited from Bitmap) |
| Dpi | (Inherited from Bitmap) |
| Format | (Overrides Bitmap.Format) |
| PixelSize | (Inherited from Bitmap) |
| Size | Gets the size of the image, in device independent pixels. (Inherited from Bitmap) |
Methods
| CopyPixels(ILockedFramebuffer, AlphaFormat) | Copies pixels to the target buffer and transcodes the pixel and alpha format if needed. (Inherited from Bitmap) |
| CopyPixels(PixelRect, IntPtr, Int32, Int32) | (Overrides Bitmap.CopyPixels(PixelRect, IntPtr, Int32, Int32)) |
| CreateScaledBitmap(PixelSize, BitmapInterpolationMode) | Creates a Bitmap scaled to a specified size from the current bitmap. (Inherited from Bitmap) |
| Decode(Stream) | |
| DecodeToHeight(Stream, Int32, BitmapInterpolationMode) | Loads a Bitmap from a stream and decodes at the desired height. Aspect ratio is maintained. This is more efficient than loading and then resizing. |
| DecodeToWidth(Stream, Int32, BitmapInterpolationMode) | Loads a WriteableBitmap from a stream and decodes at the desired width. Aspect ratio is maintained. This is more efficient than loading and then resizing. |
| Dispose() | Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Inherited from Bitmap) |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode() | Serves as the default hash function. (Inherited from Object) |
| GetType() | Gets the Type of the current instance. (Inherited from Object) |
| Lock() | |
| MemberwiseClone() | Creates a shallow copy of the current Object. (Inherited from Object) |
| Save(Stream, Nullable(Int32)) | Saves the bitmap to a stream. (Inherited from Bitmap) |
| Save(String, Nullable(Int32)) | Saves the bitmap to a file. (Inherited from Bitmap) |
| ToString() | Returns a string that represents the current object. (Inherited from Object) |
